I had contacted Upper Deck and they would not release the list of who signed. I don't get why they would care. I want to get them all and knowing there are more out there than I thought may make me buy more product.

BINGO...THAT'S why they care...and THAT'S why they won't tell anyone.

They lose the Marvel license in 3 days and they don't care anymore about the Marvel fan base. They're just trying to make every penny they can.
